Abstract
The invention discloses a computer power failure detecting instrument. The computer power failure detecting instrument comprises a single-chip microcomputer module, a voice module, an auxiliary power supply and a voltage comparator, wherein the auxiliary power supply supplies power for the modules; the voltage comparator is connected onto the power interface of a computer; the voltage comparator compares the voltage of the main board power interface with the voltage input by the auxiliary power supply, and outputs corresponding high-low electrical level; the single-chip microcomputer module is connected between the voice module and the voltage comparator, identifies the high-low electrical level output by the voltage comparator, identifies the failure point, and transfers a control signal to the voice module; the voice module identifies the control signal output by the single-chip microcomputer module, and broadcasts a corresponding failure language. Through the manner, the computer power failure detecting instrument can diagnose a computer power failure point, and is more accurate and intuitive when compared with conventional diagnosis methods.
